League Two round-up: Wilder beaten on home Northampton debut and Rochdale make up ground on top three

The top three in Sky Bet League Two remain unchanged after leading pair Chesterfield and Scunthorpe drew 1-1 on Saturday and Oxford did likewise against Bristol Rovers.

The prolific Sam Winnall gave Scunthorpe a 15th-minute lead at Glanford Park but Eoin Doyle's penalty in first-half stoppage time earned the Spireites a point which keeps them three points ahead of their opponents at the summit.

Third-placed Oxford looked set to take advantage after James Constable's 10th-minute strike but they were pegged back by Rovers' John-Joe O'Toole in the 84th minute.

Rochdale and Burton narrowed the gap behind the top three with away wins.

Fourth-placed Dale, and their striker Scott Hogan, were the division's big winners as his hat-trick earned them a 3-0 success away to AFC Wimbledon.

Southend, occupying seventh place, had substitute Conor Clifford sent off as they were beaten 2-1 away to Mansfield. Sam Clucas and James Jennings gave the Stags the points while Southend's goal came after they were down to 10 men, from Ryan Leonard in the last minute.

At the foot of the table, new Northampton boss Chris Wilder tasted defeat in his first home game in charge as they were beaten 2-0 at home by Plymouth with the goals coming from Reuben Reid and Lewis Alessandra before half-time.

Torquay, who occupy the other relegation place, saw their home game against fellow strugglers Bury postponed due to a waterlogged pitch.
